APPARATS FOB MAKING WOVEN-WI FABRICS.

Lacasse.

To all whom it may concern;

Be it known that I, WILLIAM SCHNEiDER,

, take two strands which have been intersingle operationotwice as much material as.

has heretofore een possible, the practice heretofore having been to form a strand of wire into a partially flattened helix and interweave that strand with a-receiving strand at the end of the fabric, repeating the operation until the proper length of fabric had been built up.'

The mechanism by which this result is accomplished comprises a cylindrical die having two spiral grooves. This die is stationary and has rotating within it an arbor which, for the purpose of making a partially flattened helix is in the form of a ilat blade. The wire is conveniently fed into one end of the die from opposite sides, enters the grooves and is twisted onto the arbor. The spiral grooves constantly push the completed helices oil'I the end of the arbor and draw in new wire. As a result of drawing two pieces of wire on to the same arbor at the same time the two helices are interwoven, and as they" leave. the end of the arbor they are Specification of Letters Patent. llmtnted Jun@ IU?, 11919, Application led May 31, 1917. .Serial No. 171,834.

always driven rotarily by the arbor. The delivery end of the die is positioned near to the edge of the fabric which is being woven, and as the helices emerge from the die one of them is interwoven with the receiving strand for the full width of the fabric. The

other helix does not interweave with the receiving strand, in fact but one of them can do so at one time. When the single helix is interwoven for the full width of the fabric both of the helices are cut off. rIhe fabric is fed ahead and the second strand drops down into the normal extended position and becomes the end receiving strand of the fabric and the operation is repeated.

In the drawings Figure 1 represents a View of a part of the woven fabric showing theweaving-in o eration of two strands partially complete Fig. 2 is an edge view of a complete fabric and showing the weaving in operation proceeding. p

Fig. 3 is a sectional view through the die.

Fig. 4 is a view similar to Fig. 3 but with the blade at right angles to the position shown in Fig. 3.

Fig. 5 is a side view of the die with the sleeve shown in section.

Fig. 6 is a sectional view on the line 6, 6 of Fig. 4.

eferring to the drawings, a denotes a portion of the completed fabric, b the end, or receiving strand with which a new strand ,is to be inter-woven, c, d two strands which one of a single pair of interwoven strands can be woven into the same strand of the fabric whichwould have the effect in the finished`l fabric of two adjacent strands each made up of a group of two wires. Obviously this could be repeated within reason to still further increase the number of wires in the group.

Eli

o is a flat blade or Also it is obvious that while there. has been Shown and describedthe weaving together of two strands and the interweavlng of one strand with the fabric, each of these lfabric.

In other words the word strand,` as 'here used, is to be understood as meaning either a single wire or a group of wires.

In the case where yone strand-is comprised of two or more wires the die would probably need to be equipped with a lead groove lfor each Wire of the strand.

I claim as my invention y A die for use in the manufacture o woven wire fabric comprising apair of helically formed strips interfitted with their edges spaced apart to form a pair of disconnected helical spaces therebetween, a cylindrical vsleeve against the inner face of which said `strips are closely tted to and within which said strips are rigidly secured, anda flat rotatable mandrel of a width to closely fit within said strips.
